CONSTRUCTION OF STOVES WITH ELEVATED OVENS.

Specification of Letters Patent No. 1,416 dated November 16, 1839.

To all whom it may concern:

Be it known that we, JOHN P. WILLISTON and WILLARD A. ARNOLD, ofNorthampton, in the county of Hampshire and State of Massachusetts, haveinvented an Improvement in the Manner of Constructing Cooking-Stoveswith Elevated Ovens; and we do hereby declare that the following is afull and exact description thereof.

Figure 1, in the accompanying drawing is a perspective view of ourstove, a, a, being openings for cooking utensils, immediately over thefire and b, 1), similar openings in the top plate covering the chamberleading from the fire place to the flues, in which particulars thisstove resembles many other cooking stoves now in use. No. 5 is anelevated oven, into the surrounding flue of which two pipes 2 '2 extendfrom the heated air chamber of the stove. No. 6 is a smoke pipe leadingfrom the flue of the elevated oven into a chimney and furnished with avalve or damper, the handle of which is seen at 7. No. 3 is a similarpipe leading directly from the back or heated air chamber and furnishedwith a valve, No. A. This pipemay lead into a chimney or into pipe No.6. I

Fig. 2 is a longitudinal section from front to back of the stove, No. 5being the elevated oven; 0 c, the fiue surrounding it and Nos. 10, 10,the shelves within it, all arranged as in other elevated ovens. No. 11is a pipe which may lead from pipe No. 3 into pipe No. 6 instead ofcarrying No. 3 directly into the chimney. No. 12 is a partition betweenthe back boilers to be presently described. cl, is the fire place and ethe flue or throat leading from it into the chamber under the backboilers.

Fig. 3 is a cross section from side to side of the stove, the samenumbers and letters where they occur indicating the same parts. 7, f,are two sliding shutters or dampers which are governed by the rods .8,g, g, be-- ing the stationary parts of a partition crossing the chamberof which f, f, constitutes the movable portion actuated by the handle 8.The chamber leading from the fire chamber to the flues, we divide bypartition into three separate compartments, as indicated by the dottedlines in the top plate Fig. 1 and shown more distinctly in Fig. 4,

which is a representation of these chambers, the top plate being removedfor the purpose of showing them. f, f, and g g are, as in Fig. 3, thestationary and the movable portions of a partition running across thechamber and dividing it into a front and a back compartment, the pipesNos. 2, 2 and 3 leading from this compartment through openings in thetop plate, as indicated by the dotted lines. No. 12 is a partitionleading from the middle of this cross partition toward the front of thestove and dividing the boiler chamber, into two compartments. Wheneither of the sliding shutters f are closed the draft from the fire tothe flues is arrested through the compartment to which said shutterappertains and the other being open the whole draft will pass throughthat compartment and operate exclusively upon any cooking vessel exposedto it. This affords an opportunity of, directing the whole draft uponone vessel and at the same time of heating the oven through both theflues leading up to it, as they both open into the heated aircompartment h, h, which extends entirely across the stove. c

Having thus fully'described the manner in which We construct our cookingstove with an elevated oven, we do hereby declare that we do not claimto be the inventors of the elevated oven; nor do we claim the dividingof the chamber which leads from the fire chamber to the smoke pipe intothree separate chambers governed by valves for the purpose of directingthe draft under either or both of the upper boilers, as herein setforth, this having been previously done but What we do claim is Ourimprovement in the manner in which we have combined an elevated ovenwith a stove so divided by carrying the heated air compartment hi, it,entirely across the stove and allowing the flues 2, 2, of the elevatedoven to open into it, by which means the perfect action of the oven issecured although the draft may be directed under one of the upperboilers only.
